Operation Loading- Records of varying diameter are placed intermixed inthe storage magazine B one in each cradle I9. All cradles need not befilled, and only those containing records will function. A record,resting on rollers 22, engages and depresses grooved block 26 closingcontacts 29 to 32 of switch 242 through which switches 22| are connectedto line 240. Grooved block 25 also supports record in an uprightposition. The connection of all relays 23| and 232 to line 240 isthrough switches 242 and. 22|. Cradles i9 in which there are no records,and contacts 29 tc 32 of switch 242 which have not been closed, are

` inoperative.

Selection of records-Turn the indicator of cradle I9. Each switch 22| isconnected to ak r'elay odd numbers' to relay 23 i and evenl num'- b'erstol relay 232.

Playing the record- The preesel'ected records will'. playnumerical-sequence.. The cradles |51, each with a record having. ano'ddvand even nurnber'ed selection, are' pivoted from storageY magazineB to a playing: position and returned at? the en'd of thev selection.YOdd-numberedselections,`

and even-numberedy selections consecutive with them, are the two' sidesofi the same recordi the secondside of which,-ii selected, plays beforebeing returned to the storage magazine B'. With the return ofr the lastselection' to the storage magazine.` B, the' device automatically'returns tonormal` ready again for pre-selection of another' group.. Any'selection; maybe' rejected while'playing, to be followed byv the: nextselection in the sequence.

CarrierY Cf, ini the start positionr between end plate |2 and nearestend cradle IS, and to which it always returns automatically afterplaying the last selection, holds switch |85 open. After all selectionshave been made, turn indicator of switch 220' to play position'. Inpassing from select to play positions, contact |49 is meinentarilyclosed through which' coil |48' of' relay 235 is energized closingcontact |43 and Illb' and opening contact' |4'l1.y Relay 235 holdsclosed through its contact |46. Power unit si, energized through.contact Mib; rotates threaded shaftsY l@ and |.5b the forward direction,and carrier Cv advances along cradles I9 of storage magazine B throughengagement ofv threaded? bores 3S oftubes 36 with threaded shafts l5. Asthe carrier C lines up with the" first record selected, the brushes.|4'| and |44 make contactwithf the rings |42 and |45 connecting relay231i toV relay 233 if anv odd selection has been madey and relay 232 torelay 234 if' an even numbered selection has been made'.

Placing carrier C in a playing position centered on' a cradle- |51` isaccomplished by energizing' either relays 233 or 234i which de-energizespower unit 9| byv opening circuit through either contact |52 or |56.Power unit |55 is energizedl by" the closing of either` contact |53' of'relay'' or |5= of relay 234. Rotation of power unit m5 is innv parted tokeyed' shafts Hib and |'d through' the Simultaneous with the aboveoperation, record.

rotating means assembly c is' lowered by record rotating.A means controlcam d' which is feathered" by keyed shaft l'b s'o that' as storagemechanism B approaches base It, either of' record drive Wheels 'i5 or16L engage' the record, clasping itsecurely between rollers 22 andwheels 'l5 or T6 depending uponthe record diameter.

With storage mechanism Bv securely in position on base i6, lever 2S isrotated counter-clockwise about pin 25 removing grooved block Zeri-om'record, andY record rotating means control cam d rotates free of recordrotating' meansA assembly c.

Cam-operated switch 24|` on shaft |I`5 opens' contact |158 and closescontacts |84 and |81v when storage mechanism' B and' rotating meansassembly c reach the' playing position. Opening of contact tin:zie-energizesi power unit andv shafts |65 and 16d come tol rest.Energized relay 233' or 2'34 has closed contact |54 or" |58 throughwhich power unit lun; is energized causing. record rotation in thecorrect direction throughthe linkage with keyedshaft'la. Fly wheel H32,revolving. on: shaft |621,v tends to maintain uniformv speed.-

Reversible power unit 98' is enerigized` through. either contact |54 ofrelay' 233 or- |58 of relayv 234; causing keyed' shaft |66,V towhichpower uniti 98r is` connected, to rotate in the correct direc tion.

Inner' clutch race: 58,. feathered to keyed shaft' |6, rotates cam andouter clutch race 62 through clutch balls 63 when power unit isenergized through relay 233' and rotates cam and outer clutch race 6|when power unit is energized through relay 234. Cam followers 5| on tonearms 45EL and 45b are in cam grooves V when tone arms are in a feed-inposition,. the conical point of? which rests. on the bottoms of camgrooves V resisting the force of springs 46;

Approximately C4 of cam groove Vis concentric' with shaft Hic, thebottom of' the groove VV for this segment inclining or tapering towardsthe center ofthe assembly.

As either cam 6| or 62 revolves, follower. 5|, resting in and' on bottomof cam groove V` maintains the position ot tone arm 451et or 4|b aboutthe axis of tube 40 as the concentric segment of the groove V isfollowed?, and either' tone arm 45a or 45b to pivot about screw 44'toward center so that stylus 58 is placed on starting groove ofrecords'. The various record sizesacconnnodated by this apparatusallhave a common tone' arm' feed-in position which is the intersectionof all? the record starting grooves.

The cams 6| or 62 are rotated' by shaft |H6 through a cycle of at theend of which the cam followers 5| are free of the cam grooves V and theconicalV points' of the followers 55| are on the bottoms of the grooveswhenI the cams have rotated' approximately 175.*7 thev stylus of eithertone armcomestorest'in' the record' starting' groove, andt the"inwardpressure caused by springs 46 now is resisted by the stylus inthe' rcord groove.

At completion of V180" cycle by cams 6| or 62, switches w52* or' |95bisactu'ated by' their respective cams in grooves t and u l cams 611 and62 opening contacts |35 to' |52h of switch |959 and contacts |88 to |9|boty switch |9511, and closing contacts |92b of switch |95b. Opening ofeither contact |85 o'r |881 degenergizes' power unit 98 and stopsrotation'y of shaft H5c andv either of cams El' or 62.

The* stylus in the recordgroove carries either tone arm 455er 45b upwardacross record toward the record end groove.

Shields 54' and 55 rotate about axis of trunnions 42' or s3 betweenVselenium tube shields 8'! andI bulb shield 85";V With thestylusk in therecord end4 groove the apertures 56 and 5T each coincide with aperturesp and q in bulb shield 86', ad'- mitting light from bulb 85 throughaperturesv o and T in selenium tubeshields' 8T to selenium tubes 84? and855 which operate photronic relays |75 or` lit closing Contact |71 or'|16. This energizes either relay 236 or23'l which is held closed ers 5|engages the sloping grooved surface V of cams 6| or 62 and are forcedoutward against spring 46. Stylus 50 of tone arms 45a or 451 is raisedfrom record and held stationary about axis of tube 3|) by follower 5|point in grooves. As either cam 6| or 62 rotate, followers 5| aredirected by outer fia-nge of groove V, returning tone arms 451L or 451tc feed-in position.

At completion of 180 cycle by either cam 6| or 62, switches |35a or|351J are actuated by their respective cams in grooves t and u in cams6| and 62 opening contacts |86, |90 and |92a of switch' |952, andcontacts |89 and I9!n of switch |951), and closing contacts |82 and|921j of switch |95a and contacts |33 and |9|b of switch |9511. Openingof contacts |89 and |86 de-energizes power unit 98 stopping rotation.

If the foregoing selection is odd numbered and is consecutively followedby an even numbered selection, contact |96 of switch |35a is open at thecompletion of cycle by cam 6| which has just returned the tone arm 451from the end of the odd numbered selection. Contact |66 of relay 236 isopen. A

There is current through the 232 relay energizing coil |13 and openingcontact |14 of relay 238. Thus the circuit to the 23| relay is open andit returns to normal. Relay 236 is de-energized, its contacts returningto normal, preventing the energizing of power unit |65 and the return ofcradle I9 to the storage magazine B. Contact 221 of relay 23| is closed,which closes circuit to relay 232 through its Contact |38. Contact |63of relay 236 and contact |18 of relay 231 are both open, preventingenergizing of power unit |05 and the return of cradle I9 to storagemagazine B. Power unit 98 is energized through closed contact |58 ofrelay 234 and contact |81 of switch 24| which cycles, placing tone armi4 on record. At the end of the selection, photronic relay |16 closescontact |18 whichholds through' its Contact |68, energizing power unit|05 which is described herein below.

Power unit |05 is energized through either contact |63 of relay 236 orcontact |10 of relay 231, which is closed, and either contact |82 ofswitch |95a or contact |83 of switch |951 which is closed by completionof cycle by cams 6| or 62.

Rotation of power unit |85 is imparted to keyed shafts |61) and i6dthrough the arrangement of cams H3 and H4 and levers H8, H9, |20 and12|. The hook end of yoke 8,2 of cradle operating mechanism assembly e,feathered to keyed shaft |6d and rotating clockwise, causes storagemechanism B to rotate counter-clockwise about pivot 26. Rotation ofstorage mechanism B lifts record rotating means assembly c, still incontact with record, clockwise about keyed shaft I6, until lever 2=6rotating clockwise about pin 25 is free of base |6. When grooved block28 engages record and holds same upright as record rotating meanscontrol cam d rotates clockwise, engages record rotating means assemblyc, disengaging it from record.

Cradle i9 of storage mechanism B comes to rest on base I against stop 33as cradle operating mechanism assembly e is lifted free of rollers 23and cradle I8. Y

Cam operated switch24l, on shaft H5, opens contacts |84, |81, |553, ||1,|5|c and closes contacts |50 at completion 0f 180 cycle of shaft H5.Contact |12 on relay 231, or contact |65 on relay 236, and contacts|5|aand |5|1 on switch 24| are open.

This opens the circuit through switch 2| 9 to and de-energizes andreturns to normal relay 23| or 232 which initiated the operation.Through opening of contact 226 of relay 23| or contact |30 of relay 232,relays 233 or 234 are cle-energized, opening contacts |54 and |53 ofrelay 233, contacts |58 and |51 of relay 234, and closing contact |52 ofrelay 233 and contact |56 of relay 234. Closing contact |53 or |51 openscircuit to power unit |05 which is de-energized and stops.

Closing of contact |52 of relay 233 or contact |56 of relay 234 closescircuit to power unit`9| through contact |3111 of relay 235, whichresumes rotation in a forward direction repeating the above sequence foreach selection made.

Opening contact |54 or |58 opens circuit to relay236 or 231 which arede-energized and returned to normal opening contacts |6|, |62 and |63 ofrelay 236 or contacts |68, |68 and |18 of relay 231 and closing contacts|64, |65 and |66 of relay 236 or contacts |1| and |12 of relay 231.

After all selections have been played, the carrier C will continue totravel in a forward direction towards end plate until at the end of itstravel switch |19 is open, which opens the circuit to coil |48 of relay235. Through the holding contact |46, relay 235 is de-energized. Contact|41b opens the forward circuit and closes the return circuit throughcontact |4111, reversing the power unit 9| and direction of rotation ofshafts l5a and |51. Carrier C is then returned to the starting positionwhere frame 35 in Contact with switch opens and holds open circuit topower unit 9| which is de-energized and stops.

Interruption to service.-Should current failure occur while power units98 or |65 are energized, it is necessary to complete their cycles uponresumption of service. Current failure opens relays 23| and 232 whichcancel all preselections not played. When selector` switch 229 is turnedwith indicator to off position, it connects line 240 to contact |5|c ofswitch 24| which is closed when power unit |05 is in cycle.

Through contact |5|c and contact |9211, power unit 98 is energized,which upon completion of its cycle opens its contact |92 and closes itscontact |921), energizing power unit 98 through contact |9`|a reversingpower unit 98 rotation. Thus tone arms 45e and 451 are returned tofeed-in position through cams 6| and 62. Upon completion of the cycle,contact |9|a opens and contact |9|b closes, connecting line 240 to cyclemotor |65.` ICompletion of the cycle of power unit |35 opens contact |5|of switch 24| and opens the circuit. i

The apparatus has now had its components returned to normal and is readyfor re-use, eX- cept carrier C which will return to starting positionwhen indicator switch is turned to select position and while selectionsare being made.

4 Record rejection-To reject a record selection while playingmomentarily, close switch |93. This will energize the photorelaycircuits 236 and 231, through which power unit '98 is energized and tonearm returned to feed-in position. The next selection will then play.

Any suitable record disk may be employed. In View of the fact that thedisk is supported on edge and rotated by means engaging the edge, it isdesirable to omit the central opening that normally appears in a recorddisk and to thus provide an imperforate disk. This not only increasesthe capacity of the record disk, but also provides highly useful spacein the center for the use of a label, etc. In the-illustration given inFig. 9,

the disk 251i isshown providedwith a rubber `tiro lThe resilient bodythus :provided serves :not only as aprotection for :the `disk butfacilitates the irotation thereof in fthe mechanism shown. The 'tirespanschips or nicks .in the peripheral edge `of the disk and provides asmooth track for engagement with the drivewheels, etc. 'It will beunderstood that the tire 25| may be formed `of any suitable material andmay, if `desired, be formed as an integral part of the disk 250.

While ,in the vspecilic embodiments illustrated, fthe cradles, forreceiving 'the records are shown mounted for tilting movement upon aframe, it will be understood that they may be mounted for movement inother directions, as, for example, by sliding-thereiadles longitudinallyalong a cen- ,trai support so V'that `inthe playing of a selectedrecord, the cradles or their records on their side of the selectedrecord -may loe-moved longitudinally to :free 'a space -aboutf-therecord for lthe playing-thereof-infposition.

In the foregoing description, I have .set forth a .specific embodimentof the invention in great detail for the purpose of illustrating onefmode of use ,of -the invention; itwill be understood, however, thatsuch-details may be varied widely lby those skilled in the art withoutdeparting from thespirit of myinvention.
